Abstract (en)
[origin: EP1900497A1] Machine for extruding a viscoelastic material, comprising a large-diameter screw (2) with openings communicating with a coaxial small-diameter screw (3) via a perforated tube (4), comprises an opening (42) in the end wall (43) of the large-diameter screw's housing that communicates with a discharge outlet (52) having a removable closure (61). An independent claim is also included for homogenizing and filtering a viscoelastic material using a machine as above, where material with a particle size greater than the openings in the perforated tube are discharged by opening the closure without interrupting the operation of the machine.
